The Lowdown

Alright, Rusty here, let’s have a look at what’s coming down the line for Jaconé.

We’ve got some swell on the horizon, but it’s not all go. The first few days are a bit of a write-off with onshore junk and rain, so don’t bother paddling out until later in the week. The real standouts come Thursday and then again next week Friday.

The first real session looks like Thursday, the 17th. We’ll see a clean 5ft to 6ft southerly swell building through the day, with a period stretching out to 13 seconds by the afternoon. That’s groundswell energy, and the wave energy is solid at 756 for the morning and pumping up to 1114 in the arvo. The wind will be light and cross-off from the east, keeping the faces clean. This is the pick of the first week—Thursday afternoon will be excellent for experienced surfers. That’s your go.

Friday the 18th hangs in there with a 5ft south swell (11s period) and offshore ENE wind in the morning, energy at 481. It’s good, but the wind picks up strong in the afternoon and the quality drops. Not terrible, just not as good as Thursday.

We then hit a flat spell from Saturday the 19th through to Tuesday the 24th. Swell drops under 3ft and the wind either goes onshore or stays cross-off with no punch. There are a few clean but tiny options around 3ft, but honestly, it’s ordinary. Leave the board in the car.

Then we get a nice surprise on Friday the 25th. Glassy conditions in the morning with a light NNE breeze, and a building 3ft SSW groundswell rolling in with an 11-second period. The energy’s moderate at 252, and the wind is dead flat—glassy. That’s the second standout session. Clean, fun waves for the intermediate crew, though the swell is small so don’t expect barrels.

After that, Saturday the 26th drops off again. Swell fades to 2ft with choppy sideshore winds, and it stays tiny and messy right through to the end of the month. There is a small pulse of 4ft southerly swell on Tuesday the 29th with clean conditions, but it’s not going to set the world on fire.

Water temp is about average for this time of year, so no drama with the wetsuit.

Crowds at Jaconé can be a factor sometimes, but on Thursday the 17th and especially Friday the 25th with the glass, you might find a bit of company. Worth the paddle though.

Rusty.

Information about the Jaconé Surf forecast

The above surf forecast table for Jaconé provides essential information for determining whether the surfing conditions will be good over the next 16 days. A general guide to surfing at Jaconé can be found by selecting the local surf guide option on the grey menu. Our Jaconé surf forecast is unique since it includes wave energy (power) that defines the real feel of the surf rather than just the height or the period. If you surf the same spot (Jaconé) regularly then make a mental note of the wave energy from the surf forecast table each time you go. Very soon you may start to choose your surf days based on the wave energy alone combined with our forecast of favourable offshore wind conditions. Our star ratings will help here and of course you will also find the usual wave height and period predictions on our surf forecasts as well as a full break down of the swell components under our advanced users option (to reveal that, click the little Einstein character under the tide times).

Further information to help with frequently asked questions about our surf forecast for Jaconé may be found under the help tab on the top menu and also by moving your mouse over the question marks on the surf forecast table itself. Please always bear in mind that the forecast is for near-shore open water and local factors at each surf break influence the actual breaking wave height, such as the beach / reef profile, water depths offshore and shelter.

Jacone is 14 km (9 miles) from the city of Saquarema. If you plan a holiday in Rio de Janeiro, look for hotels and other accommodation in Saquarema. Saquarema has rooms for a wide range of budgets as well as car hire and transport links.
